Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned rmyndharis/antigravity-skills at 3eff4af253.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill provides guidance and examples for implementing common JavaScript testing patterns. It helps developers write more maintainable, readable, and robust tests using techniques like mocking, stubbing, and test doubles. The goal is to improve the quality of JavaScript code through effective testing strategies.

When to use it

  • When refactoring existing JavaScript code and needing to create or update unit tests.
  • During the development of new JavaScript modules where comprehensive testing is required.
  • To learn and apply best practices for writing clean, efficient, and reliable JavaScript tests.
  • When encountering difficulties in isolating dependencies during testing.

Key capabilities

  • Guidance on mocking techniques
  • Examples of stubbing implementations
  • Explanation of test doubles usage
  • Best practices for maintainable tests

Example prompts

  • "Show me an example of how to mock a function call in Jest."
  • "Explain the difference between a stub and a mock in JavaScript testing."
  • "Give me some best practices for writing readable unit tests with test doubles."

Tips & gotchas

This skill assumes basic familiarity with JavaScript and testing frameworks like Jest or Mocha. The effectiveness of the patterns depends on understanding the underlying code being tested; it doesn't provide solutions for complex application logic issues.
